Both the Ethernet and wireless are supported by Arch out of the box. All the available Intel wireless cards are very well supported, including good powersaving. The Lenovo branded (Realtek) card does not work as well and does not support powersaving on Linux.

=== Ericsson H5321 GW Mobile Broadband modem ===

The Mobile Broadband modem may need the following change to be made into module settings so that mobile data starts to work.

GUI (X)

Also, I am going to assume that you have the same set-up as me so you'll need to do the following items.

I was in process of configuring Bumblebee, but after trying it both ways on my T530 - I don't really see a huge gain for the pain. So I dropped it. In my specific case, if I really need the extension to the battery life, you can just turn off the Dedicated card in the BIOS.

Once you reboot - you should be good-to-go with both vertical and horizontal scrolling while holding the middle TrackPoint button.

Hotkeys (Media Keys)

Media keys that work out of the box:

Wireless On/Off

Backlight Brightness (If you use the nVidia driver, configuration will be needed - documented on the Nvidia wiki page)

Thinklight / Keyboard Backlighting

Sleep

Keys that do not work out of the box, depending on your DE (you can bind them):

Mute

Vol+/-

Prev/PlayPause/Next

Lock

Mic Mute (doesn't even register on my keymapper)

Fn+F7 - Display Toggle (Projector?)

Fn+F6 - WebCam Toggle

Launcher (right of the Mic Mute)

Keybindings

Install the xbindkeys packages from the community repo. To run xbindkeys, it will want you to have a .xbindkeysrc file and will offer the default. Personally, I think the default options are terrible for a US layout (example: Rebinding Ctrl-F to not be find). So I just make my own to make it to my liking.

Here are the main ones, just open your preferred file editor and save the following as ~/.xbindkeysrc:

Be sure to set xbindkeys to run at startup, and any time you edit the file you need to restart the process. In Gnome/Cinnamon hit Alt+F2 and type "gnome-session-properties" and hit enter. Click "Add" and type in xbindkeys for the command. You can call it and describe it however you want.

If I get time, I plan to make a script that will change the program the PlayPause/Prev/Next control. This will just do banshee in my example, but I would like to expand that to control VLC if it is open and banshee is not.

Networking

Ericsson H5321 GW Mobile Broadband modem

The Mobile Broadband modem may need the following change to be made into module settings so that mobile data starts to work.

echo options cdc_ncm prefer_mbim=N >> /etc/modprobe.d/cdc_ncm.conf

Thinkpad Specific Modules

While many of the system resources will be realized by the system, you may want to add the thinkpad_acpi module to boot.

sudo echo thinkpad_acpi > /etc/modules-load.d/thinkpad.conf

This will let you check fan speeds and such with

cat /proc/acpi/ibm/fan

Battery Usage for T530

As a barometer, my Arch system uses about 6.9 watts (as per Powertop) at idle with minimum screen brightness wifi connected. My Fedora install uses about 10 watts idle, and my Windows 7 install uses about 8 watts idle according to the lenovo power manager. Tips to extend battery life:

Install powertop and run it as root. Pay special attention to any applications (as opposed to system processes) which cause CPU wakeups. I have had a clipboard manager use .5 watts on its own, so pay special attention to any apps or services you use. Also pay attention to bluetooth and network devices so you can disable them.

Use Integrated Graphics mode under Display in the BIOS setup. Even with Nvidia Optimus selected, no applications launched with 'optirun' and the card OFF as listed by

cat /proc/acpi/bbswitch

Powertop still consistently reports .3 watts more idle usage than with Integrated Graphics only mode set in BIOS. If you run Optimus, use

cat /proc/acpi/bbswitch

to check the power status of the nvidia card, and use

echo OFF >> /proc/acpi/bbswitch

to disable it. The power consumption is noticeably less than having the discrete card enabled, but still higher than the Intel card alone. NOTE: You may have to unload the nvidia module first before turning it off: 'rmmod nvidia' as root...

Laptop-mode-tools: Install/enable as per the wiki. Nearly all options work fine for the T530. For some reason, the ethernet device (enp0s25) uses upwards of a watt on my system. Laptop-mode-tools doesnt seem to disable this by default, even with /etc/laptop-mode/conf.d/ethernet.conf properly labeled with my ethernet device. If powertop reports such usage, go to /etc/laptop-mode/conf.d/exec-commands.conf and change:

profile-sync-daemon available in the AUR. When using the web browser on battery, write operations for cache, etc will wakeup the hard drive. profile-sync-daemon allows all write operations to go to RAM (as the profile is stored there), and then syncs to disk every hour (configurable). This will also reduce the wear on your hard drive, make the web browser feel faster, and reduce write cycles for SSD users.

Use 'noatime' in /etc/fstab if access times arent important to you. This is another way to reduce write cycles, and thereby disk wakeups.

Dont use any compositing at all. I tried using compton for panel transparency and this increased power consumption consistently by 4-4.5 watts idle using just the Intel card. Powertop will inform you of gpu operations as well.
